London , England -LRB- CNN -RRB- -- The three Pakistani cricket players at the center of a betting scandal have been summoned to meet their country 's top cricket authorities in London , England , where the alleged fixing took place , team manager Yawar Saeed told CNN on Tuesday .

Salman Butt , Mohammed Asif and Mohammed Amir may remain in London for two days for meetings with the chairman of the Pakistan Cricket Board , their manager said .

They have not been arrested , suspended , or summoned for further questioning by police , Saeed said .

Saeed made his remarks two days after allegations surfaced that gamblers fixed part of a Pakistan match against England last week .

Separately , customs authorities said Tuesday that three people were arrested Sunday in connection with the scandal .

They were held on suspicion of money-laundering , a representative of Her Majesty 's Revenue and Customs told CNN .

The head of cricket 's world governing body said Tuesday he wants disciplinary action within days if anyone on the Pakistan team was involved in the alleged betting scheme .

Haroon Lorgat , chief executive of the International Cricket Council , said he wants any action taken by Thursday , if at all possible , an ICC spokesman told CNN .

`` The integrity of the game is of paramount importance , '' Lorgat said in a statement . `` Prompt and decisive action will be taken against those who seek to harm it . However , the facts must first be established through a thorough investigation and it is important to respect the right of due process when addressing serious allegations of this sort . ''

Investigators from the ICC , the sport 's governing body , are already in the United Kingdom making inquiries into the allegations , the council said Tuesday .

The investigators , from the council 's Anti-Corruption and Security Unit , are working with London 's Metropolitan Police on their criminal investigation , the council said .

Federal investigators from Pakistan had been expected to arrive in England on Tuesday to look into the alleged scandal , but Pakistani Interior Minister Rehman Malik later said their plans changed .

`` We have requested Interpol and Scotland Yard to provide us with -LSB- the -RSB- preliminary report , and we have asked for permission to send our team there , '' Malik told CNN . `` The moment we get permission , we will send them . ''

Lorgat said that if any players are found guilty , `` the ICC will ensure that the appropriate punishment is handed out . We will not tolerate corruption in this great game . ''

Police have questioned four people over the scandal , Pakistani manager Saeed said Sunday . The four are Saeed , team captain Salman Butt , and two players , he said .

The alleged scandal came to light Sunday when a British tabloid newspaper reported that two Pakistan players deliberately bowled `` no balls '' -- fouls -- during their four-day series with England .

A `` no ball '' is when the bowler -- the equivalent of a pitcher in baseball -- steps over the line as he unleashes the ball . The batting team gets a run when that happens .

The News of the World posted video of what it said was an undercover reporter meeting with a man identified as Mazhar Majeed , who tells the reporter exactly which bowlers will bowl `` no balls '' and when , then lays out 14 thick stacks of bills on a table .

The video of the meeting -- which the newspaper said took place Wednesday , the day before the match between Pakistan and England began -- is intercut with clips from the following two days , where the players perform as Majeed said they would .

The tabloid said the alleged ringleader pocketed 150,000 British pounds -LRB- $ 232,800 -RRB- in the scam .

The Met Police said a 35-year-old man was arrested late Saturday on suspicion of conspiracy to defraud bookmakers and released on bail Sunday .

Police said no date had been set for a hearing or further proceedings , but that the investigation was continuing .

Saeed did not name the two players questioned by police , but Britain 's Press Association earlier reported he identified them as bowlers Mohammad Amir and Mohammad Asif .

Police refused to confirm to CNN who was being questioned .

The Pakistani players at the center of the scandal were free to leave the country , police said Monday .

Team captain Butt said Pakistan gave 100 percent throughout the match . `` We have given our best , '' Butt said after his team lost to England .

The team manager refused to comment on the report that Pakistan players intentionally committed three fouls during the match .

`` No allegations are true until they are proved either way , '' said Saeed . `` So that this point in time they are just allegations . Let 's wait until the case is complete . ''

England beat Pakistan in the four-day match at Lord 's Cricket Ground , which ended Sunday afternoon , after the scandal broke .

Pakistan 's President Asif Ali Zardari ordered an investigation into the scandal , his spokesman said Sunday .

He directed the chairman of the Pakistan Cricket Board to submit a preliminary report `` immediately , '' Farhatullah Babar said , adding that Zardari asked to be kept informed about any British investigations as well .

It is the second allegation of corruption directed at the Pakistan cricket team this year .

Betting on cricket matches is legal in England .

CNN 's Melissa Gray in London , England , and Samson Desta in Islamabad , Pakistan , contributed to this report .
